LUBRICATOR.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application led October 25, 1911. Serial No. 656,565.

To all whom t may concern:

Be it known that I, JOHN ANDREW HAR- BIsoN, a citizen of the UnitedStates, residing at Maxwell, in the county of Colusa and State ofCalifornia, have invented new and useful Improvements in Lubricators, ofwhich the following is a specification.

This invention relates to lubricators and particularly to one designedfor the lubrication of the driving chain of a bicycle or chains, or theintermeshing gearings of any well known form of machine, the object ofthe invention being to provide a lubricator that can be readily appliedto a bicycle and positioned thereon so that the lubricant,

Y through vibrations of the machine, will be positively spread upon thechain.

Another object of the invention is to provide means for eecting anydesired discharge of the lubricant from the lubricant container. n

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several viewsFigure 1 is a side view of the lubricator. Fig. 2 is a vertical sectiontherethrough. Fig. 3 is a section on line 3 3 of Fig. 2 showing thelubricant container and the valve stem associated relatively to permitthe container to be filled with the lubricant.

In the form of the invention shown in Figs. l to 3, inclusive, of thedrawing, I provide the telescopic lubricant container and brush head 1and 2 respectively, each of which being preferably 'of cylindricalconfiguration, and as shown, the brush head 2 has operatively arrangedtherein the bristies 3. The bristles may be constructed of hair, wire orany suitable well known material which may be best adapted for thepurpose intended. The lower end of the lubricant container 1 iscontracted, being preferably of substantially conical configuration. Atthe small end of the conical portion of the container 1 is formed adischarge passage 4L by means of which a lubricant from the container lcan be discharged directly upon the bristles 3 or in the space 5 definedby the lower end of the lubricant container 1 and the inner end of thebristles 3. The space 5 may be varied in size so that differentquantities of the lubricant can be stored therein as the occasion mayrequire. To vary the capacity of the space 5 the brush head 2 and thelubricant container 1 may be adjusted relatively.

A valve 6 extends into the lubricant container 1 and is centrallydisposed therein. This valve is preferably in form of a rod which ispointed, at 7, so as to effectively seat against the walls of thedischarge opening 4. The valve is provided intermediate of its ends witha stop 8, against which one end of a helical spring 9 is seated. Theopposite end of the spring bears against the head 10 of the adjustableca member 11. This cap member is threade ly connected, at 12, with theupper end of the lubricant container and any desired adjustment of thecap can be made to regulate the proper tension of the spring 9. The head10 of the cap member is provided with a central aperture 13 in which thevalve is slidably mounted. The valve is provided with an eXtension 14which is normally disposed above the plane of the opening 13. When it isdesired to lill the container 1 with a lubricant the cap member 11 andthe lubricant container 11 are adjusted relatively so that the extension14 of the valve will be disposed in the opening 13 of said cap member.The extension 14 is provided with a fiat face 15 .which may be disposedin proper spaced relation to the walls of the opening 13 to allow forthe introduction thereinto of a lubricant filler (not shown).

As hereinbefore stated, the brush head 2 and the lubricant container 1may be adjusted relatively so that the space 5 can be varied and therebyact as a well to contain a quantity of the lubricant so that the lattermay be constantly applied to the bristles 3 of the brush. When it isdesired to use the lubricator as just described, the cap member 1l isadjusted on the lubricant container 1 so as to prevent the valve 6 frommoving only under intense vibrations. Ordinarily it is intended that thelubricator be used on a machine such as a bicycle wherein the vibrationsof the machine will be suliicient to cause an alternate seating andunseating of the valve.

I claim:

A lubricator comprising a container for the lubricant, said containerbeing provided] with a conical lower end having a discharge passage andan eXteriorly threaded upper end, a brush head slidably mounted on thelower end of said container and provided tending into the container andadapted to be operated by the vibrations of a machine. 10 Intestimonywhereof I aix my signature in presenceof two witnesses.
